Background
In the automobile production process, researchers can manufacture corresponding data control models according to the accepted fairing data (namely, the outer modeling surface data of the sample lamp) in the early development and evaluation stage of the research and development of new automobile models, and the model is manufactured to completely restore the fairing data state so as to evaluate the gaps, surface differences and overall effects designed by the fairing data under the physical condition. Wherein, the evaluation of the high-precision sample lamp is an important component of the evaluation; and only under the condition that the high-precision sample lamp meets the requirements of the precision and the appearance effect of the data control model, the high-precision sample lamp can be accurately evaluated.
Compared with the traditional sample lamp, the high-precision sample lamp has extremely high precision requirement, the precision of a single piece of the high-precision sample lamp needs to be controlled within +/-0.15 mm, and the precision of gaps and surface differences between the high-precision sample lamp and peripheral matched parts needs to be controlled within +/-0.1 mm; in addition, the appearance effect of high accuracy appearance lamp needs to satisfy the color definition requirement of fairing data, still needs the inside subassembly of lamps and lanterns of show simultaneously.
In the current prior art, the high-precision sample lamp of the data control model is generally composed of a base, a face mask and an internal component; the base is a reference of the high-precision sample lamp and an installation framework of the mask and the internal components and needs to meet precision requirements; the internal components need to meet the requirements of appearance effect of the sample lamp and are generally manufactured by a rapid forming process and a milling process; the mask is an appearance piece on the outermost side of the high-precision sample lamp and comprises a transparent mask and a black edge, the requirements of precision and appearance effect are met, and the mask is generally manufactured through a simple silica gel mold rollover process or an acrylic milling process.
In the prior art, if a mask is manufactured by adopting a simple silica gel mold rollover process, the obtained mask can meet the requirement of appearance effect, but is limited by the process, and the precision of the mask cannot reach +/-0.15 mm and can only reach +/-0.5 mm; therefore, this process has been phased out.
If adopt ya keli to mill the technology manufacturing face guard, the face guard that makes although can satisfy the required precision, but along with the increase of the molding complexity of lamp housing, be subject to milling technology, the lamp housing is inside unable to be accomplished through once milling, the interior portion of digging that can't mill need mill the back alone and bond on transparent face guard, the bonding seam is very easily cracked, can not reach the outward appearance effect requirement, reflection decorative pattern on the face guard also can't be through milling the preparation simultaneously, and the face guard black border is through manual colour separation, the effect is not according with true state. In addition, the acrylic milling process has a long manufacturing period and a high rejection rate, and the problems all cause the increase of the manufacturing cost of the part.
Therefore, the mask manufactured by adopting the traditional simple silica gel mold turnover process or the acrylic milling process can not meet the manufacturing requirement of high-precision sample lamps with more and more complex new shapes; and the base and the face mask of the high-precision sample lamp are assembled by gluing in the prior art, so that the repeated precision is poor, the assembly error is high, and the precision requirement of a single piece plus or minus 0.4mm can only be met.
Therefore, in order to meet the manufacturing requirements of the high-precision automobile model sample lamp, the invention expects to obtain a novel high-precision trial-manufacturing method of the automobile model sample lamp, and the high-precision automobile model sample lamp meeting the requirements of evaluating the overall dimension and the appearance effect of the data control model in the trial-manufacturing stage can be effectively prepared by reasonably combining different processes and utilizing the complementary advantages of the different processes.
